RAWALPINDI, Pakistan, Dec. 18—President Agha Mohammad Yahya Khan today asked Zulfikar Ali Bhutto, the Deputy Prime Minister and Foreign Minister, to return immediately from the United States to form a new government.

“On the arrival of Mr. Bhutto, power will be transferred to a representative government formed under the new constitution,” an official statement said.

The announcement did not say what form the new constitution and government would take. Last night the President issued an outline of a new constitution and then withdrew it a few minutes later. The document had been written as ill East Pakistan were still an integral part of the nation.

There were continuing indications today of political turmoil in West Pakistan, all related to the announcement yesterday, that President Yahya Khan had accepted an Indian cease‐fire offer.

Editorials Assail Him

The President was denounced at angry demonstrations in various cities, by newspaper editorials and even by politicians who owe the little authority they have to him.

A particularly bitter statement was issued by a coalition of minor right‐wing parties headed by Nurul Amin, the aging Bengali whom President Yahya Khan on Dec. 8 designated as Prime Minister.

Mr. Nurul Amin said later that he would not take office.

The statement by his party demanded President Yahya Khan's immediate resignation and said:

“The tragedy of East Pakistan, the intolerable and humiliating manner in which the national army was forced to surrender its arms and the order of cease‐fire against the sentiments of the people are the logical results of the policies, Agha Mohammed Yahya Khan has been following over the last three years.”

“Internally,” the statement continued, “these policies have also led the country to a civil war and encouraged India to commit aggressions against our fatherland. Internationally, we were not able to muster sufficient assistance. Finally, our proud and brave army of East Pakistan was confronted with a difficult surrender situation and tremendous odds and had to face a humiliating disaster.

“In that situation we demand that President Yahya Khan should install a national government and forthwith resign his office,” it said.

Actually although many Pakistanis could sympathize with the tone of the statement, it was apparent that Mr. Amin has no political future.

He was selected as a figure head so that Pakistan could nominally have an East Pakistani Prime Minister.

It was not clear today whether the war with India in fact was completely over de spite the cease‐fire that went into effect last night.

Pakistan tonight accused India of having violated the cease‐fire and denied Indian charges that Pakistan had committed six violations.

A Pakistani communiqué said Pakistan was showing “enormous patience in the face of repeated violations” by the Indians, especially in the Rajas than sector of India.

The note denied any Pakistani violations of the cease‐fire “in Sialkot or any place else.”

Meanwhile, Pakistan Inter national Airlines announced tonight that service would resume domestically tomorrow and that its flights from Karachi to Jiddah, Saudi Arabia, and Nairobi, Kenya, would also resume.

There were sporadic reports of other incidents along the cease‐fire line where troops on both sides are said to be digging in and preparing positions against a resurgence of fighting. The cease‐fire remains to be formalized by an agreement in the United Nations.

Run on the Banks

A blackout throughout West Pakistan was still in effect to night and Pakistani fighter planes were patrolling the skies.

In some areas, students staged small demonstrations and denounced the cease‐fire. Riot policemen looked on with out interfering in most cases, and there was no violence.

Early in the day there was a run on banks throughout West Pakistan as rumors spread that the Government was about to demonetize its largest de nominations of money.

Last summer the Government did demonetize the two largest denominations because Bengali guerrillas had looted many banks in East Pakistan. The move was also aimed at forcing some large businessmen to pay income taxes they had previously evaded.

The Government denied any intention to demonetize money today, but the population was not convinced and it was very difficult to spend the largest denomination in circulation, the 50‐rupee note, which is worth $11.25.

The Government terminated all military and diplomatic briefings for newsmen today and virtually severed contact with the public, except for official announcements.

It was understood that Mr. Bhutto would arrive within a few days.

President Yahya Khan was under intense pressure last night to resign or to make it clear that he would step down from any position of real power, according to knowledgeable sources.

The President had announced in June that he would transfer power to a civilian government by the end of the year.
